Jackman's Fears During Child Abduction Filming
Hugh Jackman says he was too terrified to contemplate the thought of his own children going missing as he prepared for his latest movie.
In Prisoners the star plays Kelly Dover, whose daughter and best friend are kidnapped.
He told Sky News he did a lot of research on abduction before filming, but said he drew the line at method acting.
He said: "A lot of people assume that as a parent myself, I just go there.
"It's almost too strong an emotion to imagine your own life, it is such a visceral terrifying thing to imagine."
In the film, Jackman's character struggles with the pace of the police investigation, led by Jake Gyllenhaal, and decides to take the law into his own hands.
Jackman, who is best known for his role of Wolverine, described filming as intense but cathartic.
"As difficult as it is, as challenging as it is, when you get it right, the end of the day is like you're exhausted and you've had a fantastic bath. That kind of relaxation," he said.
He admitted the film is no easy watch, but he believes people sometimes need dark, harrowing films as much as entertainment.
"I often ask myself 'Why don't people just always go and see comedies, why do people go and see horror movies or thrillers?'
"I think there are essential fears we all have, and collectively, when we all see it, it is cathartic."
The movie is Canadian director Denis Villeneuve's first English language film.
Jackman credits the director for managing to balance the "part drama, part thinking movie, part knuckle-building film".
The thriller topped the North American box office in its opening weekend and is released in the UK this Friday.
